Objective To investigate the relationship between nuclear transcription factor-?B (NF-?B) and the preterm delivery (PRD) associated with intraamniotic infection (IAI) and the related mechanisms. Methods A total of 45 pregnant mice (gestation for 15 d) were divided into three groups (n=15 in each group): lipopolysaccharide (LPS) group, pyrrolidine dithiocarbamate (PDTC) plus LPS group, and saline group. The delivery time of the mice administered intravenously with the above in each group was observed after intravenous administration. The other 15 pregnant mice were also divided into 3 groups (n=5 in each group). At 16 h after administration, these mice were sacrificed for the detection of TNF-? and IL-8 levels in the plancenta by immunohistochemistry. Results The gestation time of group administered with LPS was longer than that of the group administered with LPS plus PDTC, but the expression levels of TNF-? and IL-8 were lower than those of the group administered with LPS plus PDTC. Conclusion NF-?B may participate in PRD associated with IAI through modulating the expressions of some cytokines.

Objective To observe the changes of visual acuity?multifocal electroretinogram (mfERG) and optical coherence tomogram(OCT) before and after successful idiopathic macular hole (IMH) surgery, and evaluate the efficiency of the IMH surgery. Methods A total of 28 eyes of 28 patients with IMH who underwent vitrectomy during February 2001 and May 2002 in our hospital were collected. visual acuity, mfERG, and OCT were examined preoperatively and 1, 3, 6, and 12 months postoperatively, respectively. The results were analyzed statistically compared with 33 eyes in control group. Results (1) OCT showed that 27 eyes (96.43%) had anatomic closure of the macular hole 1 month after the surgery without recurrence in 12 months. Just 1 eye (3.57%) failed in the closure within 1 year. (2) The visual acuity was much higher in the eyes 1 year after surgery, especially within 6 months postoperatively, than that before the vitrectomy(P

Objective To explore the mediating effect and moderating effect of professional psycho?logical help?seeking intention and self?efficacy between mental symptoms and professional psychological help?seeking behavior in Chinese adults. Methods Totally 618 adult samples were selected on the internet and completed measures of help?seeking questionnaire,ISCI,SCL?90 and GSES. Results Females and middle a?dulthood subjects got higher ISCI and GSES scores than males and early adulthood subjects ((82.7±6.7) vs (77.8±7.8),(83.9±6.2) vs (76.8±7.3);all P<0.01). SCL?90 was significantly and positively correlated with psychological help?seeking behavior( r=0.162, P<0.01).ISCI was found to mediate the association be?tween SCL?90 and psychological help?seeking behavior(effect value=-0.004,95%CI=-0.008?-0.002). GSES significantly moderated the mediating effect of ISCI( B=0.006, P<0.05). Conclusion ISCI plays a mediating role between mental symptoms and professional psychological help?seeking behavior, which was moderated by GSES in Chinese adults.

AIM: Previous studies performed with XBP-01 in vitro indicated that XBP-01 could inhibit vascular smooth muscle cells from being transformed into foam cell and could eliminate the atherosclerotic plaque in C57 BL/6J mouse. This experiment is to investigate its mechanism of eliminating plaques in vitro. METHODS: The cultured porcine artery smooth muscle cells incubated with XBP-01 of 0.1 mg/L for 24 hours after preincubated with oxidized low density lipoprotein of 15 mg/L for 72 hours in vitro. The samples were analyzed by fluorescence microscope?confocal microscope system and flow cytometry. RESULTS: Apoptosis was triggered by being incubated with oxidized low density lipoprotein and this process was accelerated additionally by being incubated with XBP-01. CONCLUSION: XBP-01 can be effective in eliminating atherosclerotic plaque by accelerating the process in which oxidized low density lipoprotein induced smooth muscle cell apoptosis

Objective To observe the effect and safety of low dose milrinone used in patients suffering from refractory heart failure and renal dysfunction. Methods Forty-two patients with refractory heart failure and renal dysfunction were divided into treatment group(21 cases ) and control group(21 cases )by random digits table. All the patients accepted a therapy of cardiac booster, diuretics and vasodilators, and treatment group also accepted the therapy of milrinone [0.375 μ g/( kg· min), 10 mg/d, for 7 days]. And then the symptom, signs, blood pressure, heart rate, heart function and renal function before and after the treatment were observed. Results The total effective rate in treatment group was 85.7%( 18/21 ) ,significantly higher than that in control group [57.1% (12/21)] (P ＜0.05＝. After treatment,the heart rate,systolic blood pressure,diastolic blood pressure,stroke volume,cardiac output and left ventricular ejection fraction in treatment group and control group improved significantly than those before treatment, and these index improved better in treatment group [(79.3 ± 12.4) beats/min vs. (85.4 ± 10.2) beats/min, ( 107.6 ± 15.4)mm Hg ( 1 mm Hg = 0.133 kPa) vs.( 119.1 ± 13.5 ) mm Hg, (60.8 ± 9.4) mm Hg vs. (65.8 ± 8.5 ) mm Hg,(66.3 ± 10.2 ) ml vs. (61.2 ± 9.3 ) ml, (5.3 ± 0.6 ) L/min vs. (4.8 ± 0.9) L/min, (56.6 ± 8.4 )% vs. (48.9 ±7.3)% ,P ＜ 0.05＝. In two groups,there were no statistical difference in renal function. Conclusions Low dose of milrinone can improve the heart function of the patients with refractory heart failure and renal dysfunction and has good renal safety.

Professor LI Ying-cun believes that pediatric internal injury cough is due to the weakness of lung and spleen and endogenous phlegm. The lung loses dispersing and descending to retrograde and cause cough; spleen deficiency produces phlegm to exist in the lung. The children have delicate organs need strengthening the body resistance, dispersing lung and invigorating spleen, supplementing qi and consolidating the exterior.ZisuDecoction is one of the TCM prescriptions that found from Dunhuang ancient medical prescriptions. Professor LI Ying-cun flexiblely uses this ancient prescription in modern clinic, which has achieved good efficacy in treatment of pediatric internal injury cough.
